WINDOW-FRAM E.

SPECIFICATION forming'l part of Letters Patent NO. 681,467, dated August 27, 1901.

'Application led January 2, 1901. Serial No. 41,865. (No model.)

l'o all whom it may concern:

Be it known that I, ROBERT WHITTON, a subject of the Queen of .Great Britain, residing at Castilian Works, 24 and 26 St. Giles street, Northampton, England, have invented new and useful Improvements in Window- Frames, of which the following is a specilication.

This invention relates to improvements in window-frames, and has for its object to provide an improved construction of frame the sashes of which are pivoted in such a manner that they can be turned upon the pivots for purposes of cleaning.

According to the invention instead of mounting the sashes in grooves in the frame of the window I form the said sashes with lateral grooves adapted to take upon guide-rods. These guide-rods are pivoted to the frame and extend from the bottom of the frame in the case of the bottom sash to, say, about the middle of the frame and in the case of the upper sash from the upper end of the frame to, say, about the middle thereof.

In lieu of the usual weights and cords I employ springs of any suitable construction,

which fit between the lateral grooves in theA sashes and the guide-rods upon which they run, the said springs being of sufficient strength to retain the window in any position to which it may be moved.

To retain the sashes firmly in the closed position, I advantageously divide the guidebars at the upper end in the case of the upp'er sash and at the lower end in the case of the lower sash, the end portions being rigidly fixed to the sash or frame. In this case it is necessary to raise or lower the sash so as to disengage the xed portion of the guide-bar from the groove in the sash before the latter can be turned upon the pivots. Furthermore, short iixed lengths of guide-bar are advantageously provided at the upper and lower ends of the frame to engage the grooves in the lower and upper sashes, respectively, when they are opened.

In the accompanying drawings, Figure 1 is a sectional elevation of a window constructed according to the invention and showing the architraves removed. Fig. 2 is a vertical section on the line 2 2, Fig. l. Fig. 3 is a view similar to Fig. 2, but showing the sashes of the window removed.l Fig. 4 is a view also similar to Fig. 2, but showing the sashes opened and turned upon their pivots. 5 is a section on the line 5 5 of Fig. 1, and Fig. 6 is a View showing an improved form of fastening. Figs. 5 and 6 are drawn to a larger scale than Figs. l to 4.

a is the window-frame, and b h the sashes thereof.

c o are the lateral grooves formed in the sashes, and d d e "e are the guide-rods with which the said lateral grooves engage. The guide-rods d d extend from the bottom of the window-frame upward to about the middle thereof, and the guide-rods e e extend from the top of the frame downward to about the Fig.

middle of the said frame, both sets of guide-A rods being pivoted, as shown at d and e, respectively, to the frame d and divided near the bottom and top, respectively, so as to leave portions f and g, which are permanently fixed to the frame d, so that the sashes when closed are firmly retained in position.

h h are the short lengths of guide-bar, which are fixed to the frame at the upper and lower ends thereof opposite or in alinement with the lower and upper guide-rods, respectively, the object of these fixed lengths of bar being to engage the grooves in the lower and upper sashes, respectively, when they are fully opened, so as to retain them in their open position. v

t' t are the springs,which are tted between the lateral grooves cin the sashes Z9 b and the guide-rods d and e, upon which they run, the said springs being of sufficient strength` to retain the window in any position to. whichit 'A sashes must be moved until they are free of the fixed portions of the guide-rods. The arrows in the drawings indicate the direction in lwhich the sashes are turned upon the guidebar pivots.

My improved construction of window-frame has the further advantage that where it is desired to reglaze a broken window, for example, the whole sash b can be slid off the guides IOO d and e, as indicated by the broken lines in Fig. 4, and sent away for repair.

In the'drawings I have shown architraves Ct attached to the frame a and projecting slightly beyond the inner edge of the said frame. As, therefore, those at the sides wlll of the lower sash and is formed at its inner en d with a fiat head 7o and at its outer end, which projects beyond the front face of the meeting-rail, with a knob 7a2, by means of which the head k' can be turned so that it can be passed through the slot in the catch j andturned at right angles, so as to hold the two rails together, as clearly shown in the figure. I

Z isa spring which is coiled around the pin k and abu ts at one end against a stop m, fixed in the lower meeting-rail, and at the other end against a stop or shoulder n upon the pin k, This spring normally holds the pin 7c in its outermost position or out of engagement with the slotted catch j..

Having now particularly described and ascertained` the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isf' 1. The combination with tl1ewindow-fra1ne, of guide-bars for the upper sash extending from points adjacentto the top of the frame downward adjacent to the center, and pivoted to said frame substantially centrally of their length, apair of guide-bars for the lower sash extending from points adjacent to the bottom of the frame upward adjacent to the center, and pivoted substantially centrally of their length to said frame, at points below the pivots ot the upper-sash guides, and upper andy lower sashes adapted to engage said guidesLwhereby said sashes can be moved upl andjzdown on said guides and can be independently swung on the pivots of said guides, substantially as described.

2. The combination with the window-frame, of guide-bars for the upper sash extending from points adjacent to the top of the frame downward adjacent to the center, and pivoted to said frame substantially centrally of their length, a pair of guide-bars for the lower sash extending from points adjacent to the bottom of the frame upward adjacent to the center, and pivoted substantially centrally of their length to said frame, at points below the pivots of the upper-sash guides, and upper and lower sashes adapted to engage said guides, whereby said sashes can be moved up and down on said guides and can be independently swung on the pivots ot' said guides, said guide-bars and sashes being provided the one with retaining devices engaging' the other to hold said sashes at any desired positions ou said guide-bars, substantially as described.

3. The combination with a window-frame, of guide-bars for one sash extending from points adjacent to the top downward adjacent to the center and guide-bars for the other sash extending from points adjacent to the bottom iupward adjacent to the center, said guide bars. being pivoted to said frame, stationary guide-bars in line with each of said pivoted guide-bars and sashes adapted to engage and slide on said guide-bars, substantially as` described.

4. Thecombination with thewindowframe, of guide-bars for the. upper sash extending from points adjacent to the top of theframe downward adjacent to the center, and pivoted to said frame substantially centrally of their length, a pair of guide-bars for the lower sash extending from points adjacent to the bottom of the frame upward adjacent to` the center, and pivoted substantially centrally of their length,to said frame,at points below thepivots of the upper-sash guides,'and upper and lower sashes adapted to engage said guides,whereby said sashes can be moved up and down on said guides and can be independently swung on the pivots of said guides, and stationary guide-bars arranged at the top and also at the bottom of said frame in line with theV upper and lower sash guides, substantially as de scribed.

5. The combination with the windowframe, of guide-bars forthe upper sash extending from points adjacent to the top of the frame downward adjacent to the center, and pivoted to said frame substantially centrally of their length, a pair of guide-bars for the lower sash extending from points adjacent to the bottom of the frame upward adjacent to the center, and pivoted substantially centrally ot'- their length to said frame at points below the pivots ot' the upper-sash guides, and upper and lower sashes adaptedo engage said guides,whereby said sashes can be moved up and down on said guides and can be independently swung on the pivotsof said guides, stationary guide bars arranged at the top and bottom` of said frame in line with the upper and lower sash guides, and springs secured to each of said sashes and engaging the guides therefor, to hold the sash in any desired position on said guides, substantially as described.
